Remarks

The WCF Web programming model allows developers to expose WCF Web services through HTTP requests that use "plain old XML" (POX) style messaging instead of SOAP-based messaging. For clients to communicate with a service using HTTP requests, an endpoint of the service must be configured with the WebHttpBinding that has the WebHttpBehavior attached to it. The Web model also requires that the individual operations are annotated with either the WebGetAttribute or the WebInvokeAttribute to bind them to a unique combination of HTTP method, such as POST (the default) or GET, and a URI path suffix, which defaults to the operation name.

Support in WCF for syndication and ASP.AJAX integration are both built on top of the Web programming model. For more information about the model, see WCF Web HTTP Programming Model.
